Embodiment Construction

[0011] Best practice:

[0012] The present invention is applied in the 8,000-ton / year differential polyester polymerization unit and the 3,000-ton / year differential polyester staple fiber spinning unit of the Chemical Fiber Plant of Tianjin Petrochemical Company. The production method adopted is:

[0013] (1) The addition of inorganic antistatic powder is 3Wt% (to PET weight ratio);

[0014] (2) Inorganic antistatic powder is modulated into 20Wt% slurry with EG (ethylene glycol);

[0015] (3) After the esterification reaction is completed, the esterified BHET monomer is pressed into the polymerization kettle with nitrogen in the normal compression polymerization stage, and the EG (ethylene glycol) slurry of the inorganic antistatic powder is dropped into the polymerization kettle after completion;

[0016] (4) The far-infrared masterbatch of 7Wt% is mixed in the antistatic polyester chip and carries out blending and spinning.

[0017] The far-infrared-antistatic polyester st...

Abstract

The invention discloses a making method of far-infrared antistatic polyester fiber, which is characterized by the following: generating BHET terephthalic glycol ester monomer after the esterifying reaction of raw PTA terephthalic acid and EG glycol ester in the heating condition; leading the material into polyaxe; adding the preparing modulated functional additive of inorganic antistat EG glycol ester slurry in the atmospheric polycondensation reaction stage; starting pressure-relief reaction after a while; generating the polyester microtome section by cooling the fondant; textiling the far-infrared-and-antistatic compound function polyester short fiber after mixing the antistatic polyester microtome section and nanometer far-infrared ceramic powder. The technological program is mature and easy to operate, which can produce everlasting far-infrared-and-antistatic compound functional polyester short fiber.

Description

technical field [0001] The invention relates to the manufacture of composite functional PET (polyethylene terephthalate) short fibers, in particular to a method for manufacturing far-infrared-antistatic polyester fibers. Background technique [0002] From the existing literature and reports, it is found that the polyester fiber with a single far-infrared function has been industrialized, and it is mostly used in warm clothes and health care products. However, the single-function far-infrared polyester fiber fabric has static electricity, which limits its application field. There is no composite multifunctional far-infrared antistatic polyester staple fiber product at home and abroad. Contents of the invention [0003] The purpose of the present invention is to manufacture polyester staple fibers with both far-infrared and antistatic functions through a reasonable and feasible method, so as to meet the market demand for special functional clothing fabrics in the textile in...
